I WANT KNOWN HOW THEY MAKE WIMAX HOTSPOT
(I KNOWN ALL THEORY PART I READ FROM WIKI AND ETC
I WANT TO KNOWN HOW IT WORK )

PLZZZZZ

Wifi-
A WiFi connection is bi-directional, meaning the process just mentioned also works in reverse. Think of it as a two-way radio communication that sends and receives radio signals in a form of radio waves. In the reverse process, the wired Ethernet supplying the Internet connectivity sends the information to a router. The router then translates the signals and transmits them to the computer's wireless adapter card.
The radios used for WiFi communication convert radio waves into binary code then convert the binary code back into radio waves. They are quite similar to the radios used for cell phones and walkie-talkies. However, WiFi radios can transmit at a higher frequency of 2.4 GHz or 5 GHz. Because of their high frequency, they can deliver more data. A WiFi uses 802.11 IEEE (Institute of Electrical and Electronics Engineers) standards. The 802.11 standards have different types; however, the 802.11a and 802.11b are the most commonly used ones.

A WiFi radio can transmit to three frequency bands. It can use any of the three frequency bands and can hop between them to help reduce interference. This is the reason why, in a wireless network, multiple devices can connect to the same wireless connection at the same time.

Sorry but i know only wifi and plz if any1 know's wimax work then plz post here.
